Introduction in Medical Prescription


The science about drugs consists of two branches of knowledge: pharmacology and pharmacy.

Pharmacology is the science about interaction between an organism and a drug.

Pharmacy is the science which studies questions of search, processing, preparation, and standardization of medicines. It includes pharmacognosy, pharmaceutical chemistry, technology of preparation of the medicinal forms, and prescription.

Prescription is a section of pharmacy, which consists of rules of prescribing and rules of preparation of drugs. Prescription is divided into pharmaceutical and medical one. Pharmaceutical prescription consists of rules of drugs preparation. Medical prescription includes the rules of drugs prescribing. Namely medical prescription has the important meaning in practical activity of the physician.


The most important terms of medical prescription are following.

^ Medicinal substance (in Latin – “substantia pharmaceutica”) is one chemical substance or chemical element which is used as medicinal remedy.

Medicinal remedy (in Latin – “medicamentum”) is natural or synthetic substance or mixture of substances which are permitted by the Ministry of Public Health Services for treatment and prophylactic of certain diseases.

^ Pharmaceutical remedy is substance or mixture of substances with determined activity and toxicity which is object for clinical test. After reception of the sanction for using in medical practice, the pharmaceutical remedy is registered in the state register of medicinal remedy.


Depending on a degree of expressiveness of their action upon an organism, all drugs are divided into three groups.

Poisonous substances (Venena, the list A). Drugs with very high toxicity are included into this group. In conditions of clinic, these drugs should be stored in a special safe constantly under the lock. After the ending of the working day this safe should be sealed up. The strict control should be carried out about an expenditure of these drugs.

Drastic substances (Heroica, the list B). Drugs, which at the use without the medical control can cause different complications, are included into this group. These drugs should be kept in a separate cupboard with an inscription "Heroica". After the ending of the working day, this cupboard should be closed.

A storage, account, and delivery of poisonous and drastic drugs should be carried out according to the rules which are approved by Ministry of Health.

Low-poisonous substances (Varia) are stored in usual cupboard according to the general rules of their storage.


The list of manufactured medicinal substances and drugs is located in the special book called Pharmacopoeia. Pharmacopoeia is the collection of State standards and the obligatory norms determining quality of medicines. In Pharmacopoeia following information is located: the description of properties, the physical and chemical qualities of medicinal remedies in alphabetic order, and the ways of definition of their suitability to the use. Also, the methods of quantitative definition of medicinal components are located in this book.

It allows on the basis of Pharmacopoeia’s specifications carry out the control over manufacture and application of drugs. In Pharmacopoeia we can find also such important information as the lists of poisonous and drastic drugs, the tables of the maximum single and daily doses for poisonous and drastic drugs (both for adults and children), conditions of storage and delivery of drugs, ways of manufacturing of medicinal forms, the methods of biological standardization and so on.

The drugs included in Pharmacopoeia are referred as officinal drugs (“officina” – “workshop”, “drugstore”).

Magistral drugs are medicines which prescribed by a physician for a particular case. They are made by the pharmacist in a drugstore (“magister” in Latin is “teacher”).


The routes of administration of drugs into organism are divided into two groups: enteral routes (through gastro-intestinal tract) and parenteral ones (passing a digestive tube). The enteral routes are peroral (by mouth), sublingual (under tongue), transbuccal (behind a cheek), into duodenum, and rectal (into rectum). The parenteral routes of drug administration are subcutaneous, intramuscular, intravenous, intra-arterial, inhalations, sub-arachnoidal, intraperitoneal, and so on.

The quantity of a drug, which is administered to the patient, is called a dose. A word “dose” is of the Greek origin and in translation to English means a “portion”. The following kinds of doses are distinguished:

  • an amount of drug for one-time perception is called single dose;

  • an amount of drug for use within day is called daily dose;

  • an amount of drug which is designed for all course of treatment is called course dose.


Elements of Latin Grammar


Almost all names of medicinal means are nouns of an average sort II declination (Barbamylum, Validolum). The names of acids are expressed by adjectives coordinated with a noun an acid: ^ Acidum nicotinicum, Acidum boricum.

The Latin names of salts are constructed according to the following principle: the cation name (alkaloid or metal) is put on the first place and is expressed by a noun in Genitive case. The name of anion is expressed by a noun in Nominative case.

The names of drugs and other words in the prescription are given according to general rules of Latin grammar. The table with endings of words, which can meet at a spelling of the prescriptions, is given below.

In prescription from names of nouns of IV declinations are used only word “spiritus”, of V declinations – “species”.

It is necessary to remember, that the pretexts “in” and “cum” require Instrumental case for a noun which is written after them, and expression “ut fiat” requires Nominative case for a noun which is written after them.


The doctors are forbidden to prescribe the prescriptions of drugs, which are not solved to application in the country, and at the request of the patients and their relatives without examination of the patient and establishment of the diagnosis.


^ Prescription: Structure and Rules of Registration


A prescription is written direction of the physician to the pharmacy about preparing and handing over medicinal forms to the patient with the indication of its use. The prescription is important medical and juridical document. For correctness of drugs’ prescriptions the doctor carries the juridical responsibility. When the medication is handing over free, the prescription is also a financial document.

The prescriptions should be written by the pen (not by pencil). The doctor should fill the all stipulated columns of the prescription blank. The doctor should put the signature and personal seal after the last prescription. Corrections in the prescriptions are not permitted.

The prescribed treatment should be entered in an out-patient card of the patient.


Rules of Dosage. Measure of Weight and Volume


In modern medical practice the doses of drugs are specified in decimal system of measurement. A unit of weight is the gramme, that is mass of 1 ml of distilled water at temperature 40 С. In the prescription it is designated as 1.0. At dosage of medicines following sizes (which are less than 1 gramme) are used: 0.1 - one decigramme; 0.01 - one centigramme; 0.001 - one milligramme; 0.0001 - one decimilligramme; 0.00001 - one centimilligramme; 0.000001 - one microgram. You should remember that the quantity of dry substances should be given in grammes.

At a spelling of the prescription the quantity of liquid substances may be indicated in milliliters, grammes or drops. Most commonly, the quantity of liquid substances is underlined in milliliters (ml). If the substance is included in structure of the medicinal form in drops, the quantity of drops is designated by the Roman digits before which «gt.» written (the reduced designation of a word “guttas” - "drops" in Instrumental case of plural), for example: “gt. V” (drops 5).


^ Rules of Registration of Prescriptions in Foreign Countries


In English countries and also in the countries where the training is carried out by English (India, Pakistan and others) the prescription is prescribed by English language on the special form or on a sheet of paper. All structural elements are indicated in the prescription, namely:

1 – Surname and name of the doctor;

2 – License qualification of doctor or him professional degree;

3 – Address of the doctor;

4 – Number of doctor office telephone;

5 – Date of registration of the prescription;

6 – Surname and name of the patient;

7 – Address of patient.

The scheme of the special form of the prescription in English countries is given at the page 8. The order of prescription registration in English countries is following.

Doctor writes the mark “R” in the right top corner, which means “to take” and below in the middle writes the name of the drug from the large letter in the Nominative case (8). In same line a doctor indicates also the dose of the drug (9) and its general amount (10) for course of treatment.

Below, in the right corner after “Stg.” (11) physician writes the detailed instruction for the patient about the use of this drug and makes the mark about the necessity of repeated assignment of the drug (12), and also about the need of its storage in the place, inaccessible for children (13).

The physician gives (14) the information about necessity of observance of the certain rules of safety in drug’s reception (for example “It is impossible to use alcohol”, “Causes drowsiness” and others). In the left corner below doctor puts the signature (15), indicates the identification data (16), and number of state registration of the license (17).

- the route of drug’s administration: subcutaneously, intramuscularly, intravenously, perorally and so on;

- frequency or time of the drug’s reception (3 times per day, before meal, at headache, before dream)



The prescription is separated from next prescription by short line. The new prescription begins with a abbreviation “Rp.:”. After last prescription doctor puts the signature.

The prescriptions of the medicinal forms can be short or full (unwrapped). The short variant is used basically for prescription of the officinal (ready-made) medicinal forms, and full - for the forms which make in a drugstore. Now the majority of drugs are manufactured by pharmaceutical industry. Therefore, they are prescribed only with short form. The examples of short and full forms of prescriptions are given in material about certain medicinal forms.

^ Rules of Prescribing of Medicinal Forms


Solid Medicinal Forms


The solid medicinal forms are powders, tablets, dragee, granules and some others.


Powders – Pulveres (Pulv.)

(Nominative case, singular – Pulvis, Genitive case, singular – Pulveris)


Powders are solid medicinal form for external or internal using. Powders are divided into dosed (commonly used for peroral administration) and non-dosed (commonly used for external application) ones.


^ Powders for External Use


The powders for external use (smallest powder – on Latin “pulvis subtilissimus”) are called on Latin “Aspersio”. This form is most commonly used for processing of injured part of skin. The weight of powder for external use may be from 5 g to 100 g or more. Powders for external use are prescribed both in full form and in short form. The powders for external use containing two or more medicinal substances are prescribed only in full form. In powders for external use, the medicinal substances can be used in pure state or in combination with indifferent (so-called form-building) substances. As form-building substances are used such substances as talc (Talcum), starch (Amylum) or zinc oxide (Zinci oxydum).


The example of prescription of powder for external use in full and in short forms is given below.


For example. Prescribe in full and in short forms of prescription 50 g of powder for external use, which contains 5% of Anaesthesinum. Use for processing of injured part of skin.

^ Full form of prescription. In full form a doctor should list the name of all ingredients of this medicinal form and indicate the quantity of all ingredients in grams.

Quantity of Anaesthesinum we calculate with following way. The general quantity of powder is 50 g. It is 100%. The quantity of Anaesthesinum we designate as x g, but we know that is 5%. On the base of these data we make following proportion:

50 g - 100%

x g - 5%

And as a result the decision of this proportion we find the necessary quantity of Anaesthesinum:

x = 50 z 5 /100 = 2.5 g

And so, we should take 2.5 g of Anaesthesinum. As form-building substance we can use any of possible substances. Let’s take starch for this purpose. We calculate the quantity of starch: 50 g – 2.5 g = 47.5 g.


Now we can prescribe this drug in full form:


Rp.: Anaesthesini 2.5

Amyli 47.5

M. f. pulv. subtilissimus

D.S. Use for processing of injured part of skin.


The order of short form of prescription for this drug is following:


Rp.: Aspersionis Anaesthesini 5% - 50.0

D.S. Use for processing of injured part of skin.


In short form of prescription first of all we write the name of medicinal form, after that – the name of medicinal substance and its percentage, after that – general quantity of powder.


Powders for Internal Use


These powders are prescribed with indication of exact single dose of medicinal substance and of general amount of powders. The weight of a powder should be not less than 0.1 g and not more than 1.0 g. If dose of medicinal substance less than 0.1 g, the indifferent substance should be added to this powder (sugar (Saccharum) or glucose (Glucosum)). The optimal weight of dosed powder is 0.3-0.5 g.

The example of dosed powders for internal use is given below.


For example. Prescribe 20 powders of Calcium gluconate (Calcii gluconas, the single dose is 0.5 g) for peroral administration 3 times per day.


Rp.: Calcii gluconatis 0.5

D. t. d. N. 20

S. Perorally 1 powder 3 times per day.


For example. Prescribe 10 powders of Papaverine hydrochloride (Papaverini hydrochloridum, the single dose is 0.02 g) for internal use
2 times daily.


Rp.: Papaverini hydrochloridi 0.02

Sacchari 0.3

M. f. pulv.

D. t. d. N. 10

S. Perorally 1 powder 2 times per day.


Tablets - Tabulettae (Tab.)

(Nominative case, singular – Tabuletta; Genetive case, singular – Tabulettae; Genetive case, plural – Tabulettarum; Instrumental case, plural – in tabulettis)


The tablets are dosed solid medicinal form which is produced by pharmaceutical plants by means of pressing of components. As a rule, tablets are used for peroral administration, but some tablets are used sublingually, or for implantation. Also, some tablets are used for preparation of solutions.

For prescribing of tablets you should know the single dose, the manufactured form (form, in which tablets are produced on the plant), and general amount of tablets which should be prescribed to patient.

If single dose of drug is more than contained in one tablet, we should prescribe for one reception necessary amount of tablets. If single dose of drug is less, than contained in one tablet, we should prescribe for one reception the necessary part of one tablet.

The tablets are prescribed only with short form of prescription.


For example. Prescribe 100 tablets which contain 0.3 g of Isoniazid (Isoniazidum, the single dose is 0.3 g) for peroral administration 3 times per day.


Rp.: Tab. Isoniazidi 0.3 N. 100

D. S. Take 1 tablet perorally 3 times per day.


Also, other variants of prescription are possible:


Rp.: Isoniazidi 0.3

D. t. d. N. 100 in tab.

S. Perorally 1 tablet 3 times per day.


Or:


Rp.: Tab. Isoniazidi 0.3

D. t. d. N. 100

S. Perorally 1 tablet 3 times per day.


A doctor can use any of these forms in prescriptions.


For tablets which contain several medicinal substances and have special name (for example, “^ Aeron”, “Allocholum” and so on), the following structure of prescription is used.


For example. Prescribe 30 tablets of “Allocholum” (the single dose is one tablet) for peroral administration 3 times per day before meal.


Rp.: Tab. “Allocholum” N. 30

D. S. Use 1 tablet perorally 3 times daily before meal.


^ Dragee (Dragee)

(Genetive case, singular – Dragee; Instrumental case, singular – Dragee)


The dragee are solid dosed medicinal form for internal use, which is produced by pharmaceutical plants by reusable stratification of medicinal and auxiliary substances on the sugar granules. The form of prescription for dragee is similar to form of prescription for tablets.


For example. Prescribe 30 dragee containing 0.025 g of Propazine (Propazinum, the single dose is 0.05 g). Take perorally 2 times per day.


Rp.: Dragee Propazini 0.025 N. 30

D. S. Take perorally 2 times per day.

____

Rp.: Propazini 0.025

D. t. d. N. 30 in dragee

S. Take perorally 1 dragee 2 times per day.

____

Rp.: Dragee Propazini 0.025

D. t. d. N. 30

S. Take perorally 1 dragee 2 times daily.


Capsules - Capsulae (Caps.)

(Nominative case, singular – Capsula; Instrumental case, plural – Capsulis)


The remedies which have unpleasant smell or taste, and irritate the mucosa, should be included into capsules. Capsule is environment for dosed powders, for granulose, pasty or liquid medicinal substances for peroral administration.

The order of prescribing of capsules is following:


For example. Prescribe 12 capsules each of which contains 0.05 g of Doxycycline hydrochloride (Doxycyclini hydrochloridum, the single dose is 0.1 g). Take perorally 1 time daily.


Rp.: Doxycyclini hydrochloridi 0.05

D. t. d. N. 12 in caps.

S. Take perorally 2 capsules 1 time daily.


Eye Membranulas - Membranulae ophthalmicae

(Nominative case, singular - Membranulae ophthalmicae, s. Lamellae, Instrumental case, singular - Membranulas ophthalmicas, s. Lamellas)


The eye membranulas are sterile polymeric plates with size of 9*4.5*0.35 mm, which contain medicinal remedies in definite doses and dissolved in tears liquid. The eye membranes can be stored in hermetically closed containers nearly 1 year.

After applying on the eye conjunctive, the dissolution of polymer is beginning.

In case of the using of eye membrane, the therapeutic concentration of medicinal remedy can be maintained during 24 hours.

In comparison with eye drops, the eye membranulas have the following advantages:

- the support of stable therapeutic concentration of medicinal remedy during long period of time;

- the high stability of medicinal form;

- the maintenance of sterility during significant period of time;

- more exact dosage of a drug.

Nowadays in medical practice the eye membranules (Membranulae ophthalmicae) with pilocarpine hydrochloride, atropine sulphate, neomycine sulphate, and other medicines are used.

The eye membranules are prescribed with short form.


For example. Prescribe 30 eye membranules, which contain Pilocarpine hydrochloride (Membranulae ophthalmicae cum Pilocarpini hydrochlorido). Use one membranula for side of a lower eyelid 1 times daily.


^ Rp.: Membranulas ophthalmicas cum Pilocarpini hydrochlorido N. 30

D.S. Use one membranula for side of a lower eyelid 1 times daily.


The home-tasks for prescription


1. Prescribe (in short and full form) 40 g of powder for external use, which contains 2% of salicylic acid (Acidum salicylicum). Use of processing of injured part of skin.

2. Prescribe 20 powders of nicotinic acid (Acidum nicotinicum, single dose is 0.03 g) for internal use 3 times per day.

Soft Medicinal Forms


The soft medicinal forms are ointments, pastes, liniments (or liquid ointments), suppositories, plasters, and creams.


^ Ointments – Unguenta (Ung.)

(Nominative case, singular – Unguentum; Genitive case, singular – Unguenti)


An ointment is soft non-dosage complex medicinal form, which has viscous homogeneous consistence and is intended for external use.

The ointments are prepared by mixing of various medicinal substances with the form-building substances, which is called as ointment bases. The ointments form an equal film (which does not slip) on a surface of a skin or mucous. As remedies in ointments are used antibiotics, hormones, salts of heavy metals, astringing, irritating, and other substances.

Animal or vegetative fats and their derivative, fat-like substances, carbohydrates, and other substances can be used as the ointments bases. Lanolin and vaseline are most frequently used among them. The bases for ointments should be indifferent, well are mixed with remedy and easily will give back them, not are changed under influence of light and heat, to not react with medicinal substances, and thaw at temperature of a body. The bases for eye ointments should be also sterile and neutral.

The amount of prescribed ointment depends on a way of its use. The eye ointments are prescribed in amount of 5-10 grammes, ointments for lips and nose - in amount of 10-20 grammes, for application on injured parts of the skin - from 15 grammes to 100 grammes and more.

Ointments are non-dosed medicinal forms. Therefore, amount of ointment in prescription is prescribed as a total unit. Simple ointments consist of two ingredients: one active and one inert substance. Complex ointments consist of more than two ingredients.

The percentage of powder-like substances in ointment should not be more then 25%. Differently, ointment turns to paste. Ointments can be prescribed in short and in full forms. Most ointments are prescribed in short form.

In short form of prescription the percentage of active substances are prescribed in percent or in mass units. The short form of prescription is begins with the word “Unguenti” (“Ung.”). After that the name of medicinal remedy is written, its concentration in percents, and general amount of ointment.

In the full form of the prescription, the names of all ingredients of this ointment are listed. The weight of substance should be indicated after the substance’s name. Also, the indication about preparation of ointment from these components (“M. f. ung.”), should be given.

For example. Prescribe 50,0 grammes of ointment which is based on vaseline (Vaselinum) and contains 1% of Tetracycline hydrochloride (Tetracyclinum hydrochloridum). Use for application on injured parts of the skin.


Rp.: Ung. Tetracyclini hydrochloridi 1% - 50.0

D.S. Use for application on injured parts of the skin.


This prescription may be written in full form:


Rp.: Tetracyclini hydrochloridi 0.5

Vaselini 49.5

M. f. ung.

D. S. Use for application on injured parts of the skin.


The ointments are widely used in ophthalmology. Slowly developing effect is the feature of eye ointments. In comparison with eye drops, the duration of eye ointments action is more. The indication “Eye ointment” should be written in signature before the indication about using.


For example. Prescribe 10.0 grammes of eye ointment with
2% of Polymyxine M sulfate (Polymyxinum M sulfas). To pawn behind lower eyelid 4 times daily.


Rp.: Ung. Polymyxini M sulfatis 2% - 10.0

D.S. Eye ointment. To pawn behind lower eyelid 4 times daily.


For example. Prescribe with short and full forms 50.0 grammes of ointment, each gram of which contains 10,000 of international units (in Latin – IU) of Erythromycine (Erythromycinum). Use for application on injured parts of the skin.


The full form:


Rp.: Erythromycini 500,000 IU

Vaselini 50.0

M.f.ung.

D.S. Use for application on injured parts of the skin.


The short form:


Rp.: Ung Erythromycini 50.0 (1,0 – 10,000 IU)

^ D.S. Use for application on injured parts of the skin.
